DL-ALANINE (15N) is an isotopically labeled alanine amino acid in which the amino nitrogen is enriched with 15N, featuring the standard amino acid backbone with a methyl side chain characteristic of alanine. The molecule bears a free primary amino group and a free carboxyl group, with stereochemistry corresponding to the DL (racemic) mixture rather than a single enantiomer. DL-ALANINE (15N) is used in isotopic tracing, NMR or MS-based analytical method development, and peptide or protein labeling workflows where incorporation of a defined 15N-containing amino acid enables tracking and quantification of nitrogen-containing species.
